What is how much do sousaphones weigh?

Sousaphones weigh between 15 and 25 pounds. The exact weight depends on factors such as the size of the instrument, the material it is made from, and any additional features or accessories. The bell and the body of the sousaphone are typically made from brass or other metals, which add to its weight. However, there are also lightweight sousaphones made from fiberglass or other materials that may weigh less than traditional brass models.
